It is because of the grace factor that we are touched by God and now live for God.
In a very practical way, the extent that we live for God directly reflects the authenticity of God’s love and grace being perfected in our lives. It is this simple. As we yield to God’s effective grace, i.e. cling to Christ, God’s Spirit does His good work in us. This is where the fullness of truth and grace are manifested in works; theology now becomes more than a practice of one’s mind, it becomes an application of one’s heart.
